# How Quietube Blocks YouTube, Reels and Distracting Apps

Modern short-form video formats (YouTube Shorts, Instagram Reels, TikTok) are
engineered around hyper-dopaminergic variable reward schedules. Quietube
prevents unintentional scrolling relapses using an advanced Android system
accessibility architecture.


THE FOCUS BLOCKER ARCHITECTURE

Quietube utilizes a specialized background accessibility service operating
directly on the device level to detect and intercept distraction triggers before
they load on screen.


WHAT GETS BLOCKED?

 * Native Social Applications: When configured, launching apps such as
   Instagram, TikTok, Snapchat, or X during an active session immediately brings
   Quietube back to the foreground.
 * Browser URL Bar Inspection: If you open mobile browsers such as Google
   Chrome, Brave, Mozilla Firefox, or Samsung Internet, the accessibility engine
   monitors the active window URL. If you navigate to short-form video feeds or
   known distracting domains, the page is intercepted and redirected
   immediately.
 * The External Video App Redirect: Quietube prevents you from opening external
   social video apps during study sessions, intercepting external intents to
   protect your focus.


WHAT HAPPENS WHEN A DISTRACTION IS INTERCEPTED?

When you attempt to open a blocked app or short-form video:

 1. The distracting interface is immediately minimized.
 2. Quietube returns to the active lecture or study timer.
 3. A calm reminder banner displays your active focus goal.
 4. The Reels Blocked counter on your Focus Insights dashboard increments by
    one, giving you tangible proof of saved study time.


PRIVACY & SAFETY ASSURANCE

Quietube's accessibility service has a strictly scoped footprint: it does not
log keystrokes, does not read chat messages, does not record passwords, and
transmits zero browsing telemetry over the network. It exclusively checks the
active app name and top browser address to keep you focused.
